The current draw on an octocopter like the S1000+ can far exceed what the PH 2.1 power module's capable of handling. Regarding the Pixhawk 1 power modules, those do not even support the voltage of a 6S battery.
Infinity Mapping yeah I agree. My only concern with in line devices is little info on how they fail. Ie could their online failure kill total aircraft power. Currently am using the factor unit but not online (so no usable amp reading) until I can find an online option with detailed info on how it fails. Not keen to have it loose power mid air.
Infinity Mapping, I would like to suggest you check out the Mauch line of sensors and becs for providing dual redundant power supplies. Just fitted the 200a Mauch Sensor to my 680pro running original pixhawk and using the provided calibration settings, I have never seen such accurate current readings. This is the first time I've been able to fully trust the reported mAh value on telemetry.
@Andrew Loerch Can you tell me that whether you connect all the 3 wire from a single ESC to the flight controller or do you avoid the 5V in all the ESC expect the 1st One, as in APM 2.8 I used to connect the 5V wire from the 1st ESC only and I remove it from the rest ESC to prevent Short circuit, is it okae to connect all 3 wires in Pixhawk , I am afraid it might short circuit, do reply .
No sensible person would run a pixhawk off the 5 volt you get from an ESC. If your ESCs provide 5 volts power then you shouldn't be using it. You should use a dedicated 5 volt power supply with enough amps.
You made the right choice, not to by the DJI flight controller. Don't get me wrong, but the DJI is not as flexible as the Pixhawk FC. I'm a huge fan of the Pixhawk FC.
We are still working on and testing all of the integration parts and haven't started on the aesthetics yet. The DJI S1000+ comes with 8 ESC cables, that connect to the front of the center frame on the bottom, and then to the Pixhawk. These cables are too short if the Pixhawk is in the forward orientation. Fortunately, ArduCopter supports many different autopilot orientations using the Board Orientation (AHRS_ORIENTATION) parameter. We set this parameter to Yaw180 before performing the accelerometer and compass calibrations. Once we are 100% satisfied with our testing (testing new PID's, retractable landing gear, auto missions, and RTK navigation) we will cover the wires with mesh, and possibly replace the ESC cables with longer ones so we can move the Pixhawk closer to the center of the aircraft and change its orientation. At the moment, however, it flies very well, even with the board rotated.
Yes that is understandable. I am testing mine pixhawk 2.1 in the next few days. Do you know if it provides 5V to the servo rail or i still need BEC to power opto ESC's?
That's a cute copter you got there
it seems an interesting project can you make a build video?
I definitely plan on writing up instructions. I might be able to do a build video if there's enough interest.
yes interested
what was your main reason for not using the supplied power modules with the PH?

Paul Atherton thanks for heads up will do. Was hoping to test fly this week but weather crazy.
Hi thanks for the suggestion! The sensor you mention (mauch 200a) is actually exactly what we're using. We've also had a very good experience with it.

@@christophertelford Yea, I bought Xrotor pro 40A , it didnt had the 5V wire, Thankz for the tip 👍🏻😇😊
@@mysterious_trash No worries;

Is your other flight controller for sale?
The DJI flight controller? I did not buy the DJI controller with the S1000+ kit, which saved me over $1k.

Why the orientation of the pixhawk is in reverse, it points backwards?

autodev the pixhawk 2.1 still needs a bec to power the rail.
